This invention relates to selection apparatus of addressing and othersimilar printing machines, of the kind in which printing plates fed intothe machine control,'by the action of indicators such asriders, tabs,projections, depressions, or'recesses located in or on the printingplates'or their holders, certain processes of the machine, such as theapplication or vwithdrawal of the printing pressure. Groups of switchesadjusted on'a selector in such apparatus have had only an individualeffector action, that is to: say, all the printing plates havingindicators which corresponded with individual switches of the group wereused for control purposes. As the indicators of a printing plate donotvall necessarily correspond with one a'djusted group of switches, thedifiiculty arises that they can'- not be uscdfor a group action, so asto augment'or manifold the adjustments and adapt them to diflerent:office organizations. An object of the present invention is to overcomethis ditliculty. a

The salient objects of this invention are to provide a selectionapparatus comprising a switching-over device that may be readilypositioned for so-called group actionor for individual action; toprovide a switching de-' vice comprising stationary and movable contactsthat maybe actuated by indicators on the printing devices; to provide aselector wherein the electrical connections will be so arranged thatpassage of the current therethrough may be regulated in order that onlydesired circuits may be closed; and to provide a selector having relaystherein so arranged in the circuits that fluttering thereof will beprevented, I i o In the accompanying drawing the invention isschematically illustrated and the electrical connections arediagrammatically shown; I a

In order that the invention may be clearly understood and readilycarried into effect, the same will nowbe described morefully withreference to the accompany drawing wherein a plurality. ofstationarycontacts 0 to o are shown as being carried by a block orblocks of insulating material 1, and arranged on these blocks in spacedrelation with the stascribed in the Duncan patent No. 1,481,860,

patented January 29, 1924,- and this feeding device sequentially movesthe printing devices a through the guideways 3 first into the selectingposition wherein the printing device a is shown and then into printingposition wherein the printing device a is shown. Impressions are madefrom the printing device a" through the suitable ink ribbon R by aplaten 5 carried by the-platen arm 6 including a bearing 7pivotally'mounted on the frame 8 of themachine. The machine alsoincludes a driving pulley 9 mounted on a shaft 10 and receiving powerthrough a belt 11 from a. suitable source of power suchi as anelectricmotor. On the shaft 10 is a crank arm 12 having alink 13 connectedthereto which is pivotally'connected at 14 to a rocker 15 pivotallymounted on the frame 8 at 16. Pivotally mounted on the rocker 15 at 17is a link 18 having a notch 19 therein, and a pin 20 ona portion of theplaten arm 6 depending below the bearing 7 thereof is=disposed in thenotch 19 to therebyconnect theplaten arm 6 to the link 18 and the rocker15 so that" as the driving pulley 9 is operated a reciprocatory movementwill be imparted to the platen 5 to therebyapply a'printing pressure.-As is well understood in the art,"the operation of the feeding device 4and the platen 5 are in timed relation'relative to each other and theprinting device is first moved through the selecting position beforemoving into printing position, and when in selecting position theselection apparatus determines whether or not the platen 5 is to beoperated,'and this is brought about in the following manner: Theindicatorspreviouslyreferred to are in the present instance tabs 22 andthe device is, in the disclosed embodiment, arranged for group action,that is, tabs, such as 22, must be in the three positions indicatedbefore the platen will be rendered operative. Detecting fingers 23' arepivotally mounted on a shaft 25 and are'disposed to be engaged by thetabs 22 on the printing device a 'in semaybe moved downwardlyinto'circuit closing position and retained therein, the plungers thereofincluding shoulders which en'- gage a suitable latchingdevice. When theplungers-of the switches e to e are moved downwardly-they close acircuitbetween the cooperating pairs of contacts that are respectivelyindicated by m to m and y to y", Conductors; t to. respectivelyinterconnect the contacts k tolc and m to :0 The 7 contacts 3 to jI areeach connected to aconsource of current i.

ductor 26 which is connected 'to one terminal of the winding offacontrollingrelay-g, a conductor 27 being connected to the other.terminalof this winding and to a conductor 29 which is connected to oneterminalof a A conductor 28'is connected tov the other terminal of thissource of current. The conductor 29' is also connected to one terminalof the winding of the operating relay 7a,: the otherv end of thiswinding being connected through a conductor 30 to the armature m of therelay g, which armature is movable between contacts p and n and whichisnormally urged into engagement with the contact p by the spring '31. Thecontact 12 is connectedrthrough a conductor-32 to the terminal 33 of theswitching-over. device, generally indicated by f. The contactn isconnected by. a conductor 35 to the contact 36 of the switching-overde-' vice f. The conductor 28 is connected to the switch blade 37 of theswitching-over device in The contact;-'3 6 of the switchingover devicef'is connected through a'conductore, to each of the'contacts 0 to 0while the contact 33 of the switching-over device is connected throughthe conductor r to each of the contacts 6 tob"; lvhentthe device is tobe arranged ,forpgroup action, the switch blade 37 is engaged with thecontact 33. A circuit, is therefore established from." the sourceofcurrentz'Jthrough the conductor 28, switch blade 37, contact 33,-'conductor 1',

to the various contacts I) to I), through the of the tabs 22 on theprinting device a in selecting position. Therefore, the dircuit will beestablished through the plungers of the switches from the contacts 00 mand m to the" contacts 3 'f and 3 and thence through the conductor 26 toone end of the winding of the relay 9 and through" the conductor 27 tothe conductor 29 and thence to the-other. terminal of the sourceofcurrent i. This energizes the controlling relay 9 and the armature m isattracted thereby and contacts with the contact n which is connected tothe contact 36 on the switching-over device f and which is thereforeisolated from the circuit. However, when a printing'device havingtabspositioned as the tabs 22, which correspond to the closed'ones of theswitches e to 6 moves into printing position the detecting fingers 23are moved, and in this instance the contacts A, 76 and k willbedisengaged from the contacts 6 b and b and therefore the circuit to thewindingofthe relay 9 will be broken, the circuit between the contacts band k and b? and k4 being opened by reason ofthe disposition of theswitches e and e. The de-energizing of the 'controlling relay 9-;permits the spring 31 to move the armature m into engagement with thecontact p and therefore an electric circuitwill be closed as followsThe, current will flow from one terminal of. the source 11 through theconductor 28, switch blade 37 to contact 33, through conductor 32,contact 1), armature m, conductor 30, winding of the relay it, throughthe conductor 29 to the other terminal of the source 2', and thereforethe operating relay b will be energized to thus attract the armature 4Owhich. is pivotally mounted at 41 on the frame Sand therefore the nose42 on this armature will be retracted from engagement with the nose 43on the dog 44 fixed on the shaft 45, which extends below the guideways3, and on the other end of the shaft 45 is a dog 46 having a roller 47thereon adapted to be engagedby the block-48 on the link v18. Prior tothe time the armature40 was attracted the nose 42 engaged the nose 43and therefore positioned the dog Hand thus the'shaft' 45, dog 46 androller 47 'so that the :block48 engaged said roller and held'the link 18in the positionil- I lustrated whereby the notch 19 was disengaged fromthe pin 20, and it is therefore .nianifest that the platen arm 6'was notcon nected to the rocker 15 and therefore was not operating. But, whenthe armature 4O meal is attracted and the noses are disengaged, thespring 49 moves the dog'44 and the arts carried thereby so thattheroller 47 isengages the block 48 and therefore the notch 19 may engagethe pin 20, and therefore the link 18 will motivate the platen arm 6 toapply printing pressure through the'platen 5,

' The block 48 will move beyond the position of the roller 47 when theplaten moves in the performance of a printing operation, and on thereturn stroke the block w1ll engage the roller and therefore the shaftand dog 44,

will be moved and the projection on the dog 44 will engage the latch 51that is urged into engaging position by the spring '52, and

when the parts are so positioned the nose 43 will have again moved belowthe nose 42 and the latch 51 will hold the parts for a short time duringthe changing of the printing devices. If a printing device similar tothe printing device a moves into selecting position, the circuit to theoperating relay It will;

again be closed o and the armature 40 will again be attracted andtherefore the spring 49 will again move the parts, as above de--scribed, to bring about interengagement of the pin 20 and the notch 19,the latch. 51*

serving to hold the parts during the timethe circuit is broken whichoccurs when the printing devices are changing. If, however,

, the printing device which moves into selecting positions does not havetabs positionedas, illustrated, the circuit to the controlling relay gwill be closed and the circuit to the relay 7:. will be opened, andtherefore the platen will not operate by reason of the engagement of thenose on the armature 40 with the nose 43 on the dog 44.

When the device is to be arranged for individual operation one or moreof the.

switches e is closed depending upon the selection desired, and theswitch blade 37 is engaged with the contact. 36 and a circuit as followsis set up: Current flows from the source-i through the conductor 28,switch blade 37, contact 36, conductor 8 to the various contacts 0 to o.A circuit will not be established however until the detecting fingers.engage tabs which cause the movable contacts to k to move, andwhen acontact, or contacts 70 to k is moved intoengagement with a contact orcontacts 0 to 0 which are connected through conductors t to t tocontacts :0 V to :0 they are connected'with contacts 3 to y" of theclosed switches. Therefore, current will flow from the engaged of k thecontacts y to 11 through the conductor but when relay 9 is'ener 'zed,asjiust set forth,- a circuit is closed. to t 'ef'operating relay in thefollowing manner; from the 7 source i through the conductor: 29, relayh,

conductor 30,4armat1irem, contact-n, for the armature m will have beenattracted by the relay 9 and will be engagingthis contact,

and from this point the, circuit is established through conductor 35 tocontact 36, "switch blade 37 and conductor 28 to the other ter- ,minalof the'source 'z', and it is therefore apparent that the operationthedog46v and roller, 47 will. be performed in a manner previously,described to control the operation of the platen 3!), for the action ofthe armature 40 in this instance will-be. the same as I, that Previouslydescribed.

. ;The selector mechanism isarranged in inoperative position bydisposing the switch blade 37 in the intermediate position ill'us .itrated. NVhen the controlling relay g is d'eenergized the spring 31holds the armature m in. engagement with v the =-contact Thus when theswitch blade 37is first moved into engagement with the contact 33 itmight be .gpossible that the operating relay 1h wouldbe energized'priorto' the time the relay .9 isenergized to attract the "armature mand .dis-

engage it from the contact p, foritis apparent that'the contact .pinthe"conductor 32, againstw hich thearmature m will have been restingpriorto energizingof the relay g, is

connected to the contact 33vand current therefor wouldfbe suppliedtolthe relayoh. This would cause a fluttering of the operating relay itwhich might result in operation there- 1 of. a This is prevented howeverby providing [much more resistance in the operating relay Lhthan in the.controlling relay g, and dueto the high resistance in the relay hcurrent'will not flowtherethrough prior to the time the. relay g is enerized and in this manner fluttering of the re ay h is, prevented.Moreover any back flow or leakage in the circuit will notbe detrimentalto the proper operation of the.

device by-reason of the difference in resistance between the relays gand h.

It is apparent from the foregoing description that I have provided aselector mechanism which may be easily arranged to either bring about agroup selection or individual selection as may be desired, and that thismay be readily controlled by a switching-over device that may be shiftedinto difierent positions that may be used to bring about different typesof operation.
